Chester,

Buy the RV Handbook by Estes. Good tire section. When Steve bought his rig I think it came with Load D tires but they were ST trailer tires. LT tires are Truck tires and diffferent than trailer tires. When you talk load range you have to talk about the same type tire LT or ST. Don't mix the two or it gets confusing.

(The tables allow you to load air in your tires for a given lbs. In theory you get better tire wear. I load mine IAW the tables.)

For example Estes has the Following in the Tire and Rim Assoc Tables:

LT235/85 16 (Load range E Truck Tires are rated at 3042 lbs@80psi)

In contrast

ST235/80 16 (Load range D TRailer Tires are rated at 3000 lbs@65psi)

So it is easy to mix them, that is why it is sometimes confusing.

Trailer tires are usually loaded to 65psi and truck tires to 80 psi.

Next time your at CW you should pick up a copy of the handbook.
